In April 2020, JAEA has been introduced Physical Protection Corrective Action Program (PPCAP) with full-scale. It was needed to introduce unified operation for six sites with different business scales, and headquarters developed the common guideline. There was an impression that physical protection activities were carried out by a limited number of employees. Therefore, a problem was to root and activate PPCAP activities among all employees in order to make them effective. Five activities were implemented to solve this problem. As a result, more than 3,700 condition reports (CR) have been collected for 4 years. This paper reports on the activities related to the PPCAP that have been implemented at JAEA.

In Japan, about 10 years have passed since the law obligated nuclear operators to develop and maintain a nuclear security culture. During this period, the global nuclear situation has changed significantly, and it is becoming important to maintain a stance that emphasizes compliance with regulations and nuclear security culture. In JAEA, the policy of legal compliance and developing nuclear security culture is determined by the president of JAEA. For legal compliance and developing nuclear security culture, many activities are carried out based on that policy. Finally, these activities are evaluated and improved it every year. Case study is the one of activities that can obtain skills for legal compliance and developing nuclear security culture, such as sensitivity of nuclear security risks, correct understanding of the laws. The procedure for the case study was created with reference to a method called KY-Training which is often applied to safety training program in Japan. KY-Training is a training that participants (groups) can reach the conclusion how to respond to cases through four questions. Firstly, participants are given illustrations and descriptions which has potential of nuclear security risks. Then, participants make discussion according to four questions. Consequently, participants can effectively become aware of nuclear security risks. In the 2022 case study, we prepared 23 cases so that they can select choose freely according to role of participants such as in charge of nuclear security, guards, general employees. Finally, participants are asked to fill a questionnaire to evaluate effectiveness of case study. The result of questionnaires indicated that the case study was able to lead to improvement sensitivity of nuclear security risks and correct understanding of the laws. Overall, case study results suggested that JAEA's efforts were implying sufficiently to develop and maintain a nuclear security culture.

About ten years have passed since the introduction of nuclear security compliance and security culture development activities. While there have been changes in domestic and international situations, it is essential for nuclear security that the entire organization maintains an attitude that emphasizes compliance with laws and regulations and nuclear security. JAEA has been effectively implementing various activities with evaluation and improvement. Especially, e-learning which combines education and awareness, case studies, and internal audits are considered effective in maintaining nuclear security compliance and security culture development activities.

Human resource development in the Nuclear Security Area

Nakamura, Hironobu

INMMJ Newsletter (Internet), 3, P. 2, 2022/04

Based on the request form INMM Japan Chapter, I summarized the subject and suggestion about human resource development for nuclear security area. We are applied the hard law for the Nuclear security to keep public safe as well as safety. In the work of nuclear security, even if the research institute such as JAEA, as well as electric company, we must satisfy the nuclear security rules corresponding to each business regulation. The basic work is the activities of compliance and nuclear security culture promotion, insider/outsider countermeasures and emergency response, etc... However, in order to implement those works, high level of compliance consciousness and ability of communication are necessary. In addition to that, human resource development for nuclear security is not only the education for the person in charge of nuclear security management but also, we implement the education (e-learning) for all workers in JAEA. Furthermore, we implement education for the law, periodical review of our rules and assessment in order to reduce the security risk as low as achievable. Basically, I think that securing human resources and development of human resources is basic approach. However, in case of human resource development for nuclear security, not only the implementation of OJT and education, but also it is very important to conduct several activities shown in above continuously.
